Devices of this character are already well known but certain disadvantages are existent therein, namely, the inability to rearrange the matrices in proper order as they leave the machine, and the matrlces are not acted upon with sufficient delicacy to avoid damage thereto.

The object of the present invention is to provide a particularly simple method and machine for cleaning matrices wherein the above objections are overcome. For this purpose the matrices are first cleaned by means of brushes at the edge, at the foot and at the toothed portion in piles in a horizontal passage capable of being drawn inwardly,

29 and 'at the same time the grease is dissolved from the wide-sides thereof. Thereupon the matrices are conducted separately by means of a matrix lifting device past brushes arranged at right angles to the feeding passage and through a drying device whereby the wide sides and the lugs are cleaned and the matrices dried. The matrices are then conducted by travellingfelt bands to a remov able collecting device in which they are again arranged in the form of a pile by means of inclined guide rails.

This method enables the matrices to be cleaned and dried eflicientlyonall six sides in one operation and by reason of the simple construction an operation. is obtained free from disturbance and asthe machine is cheap in production the owners of the smallest composing machines are in a position to utilize the advantages of the invention.

In the accompanying drawings there is illustrated one example of construction of the machine.

Figure 2 is an elevation with the matrix lifting device in the highest position. I

Figure 3 is a section of the feed passage.

Figure 4 is a side elevation of the slide.

Figure 5 is an enlarged sectional viewof the collecting device'with its supply device. 7 Figure 6 shows the matrix liftingdevic'e on a largerscalel v i f Figure 7 showsthe position of a'matrix sliding on guide rails. v g

Figures 8 and 9 show a cleaning device on a larger scale. V 1 l The machine consists of a'shallow casing divided into a number of compartments and having a front wall 1 (Figure4), and a rear wall 2. The 'front and rear walls'together 1 with a matrix slide, 3 form the feed passage. The matrix slide 3 is capable ofbeing drawn rearwardly by means of its long'shaft 4 and a handpiece 5 and can beretained in its outermost position by, a locking lever 6. When thematrix'slide'r 3 is drawn rearward ly a spring 7 is tensioned. p Y 1 In an extension of the 'feedpassage there are provided four brushes 8, 9,10 and-l1, which, as shown in Figure 3', are made'to conform with the shape of the matrices-Y In front of the brushes 8, 9', 10 and 11 there is also providedan'adjustable controlling pin 12 which can be adjusted to suitvarious types of matrices to 'becleaned'. The movementof passage'a cleaning passage 14 formed by ele Inents hereinafter described. lThe passage .of

the separate matrices through the cleaning passage 14 is effected by means of the matrix lifting device 15 which is guided. in the lower "portion of the cleani'ngpas'sageby a guide member 16 and isconnected by a 'crankrod V 17 to a crank 18.Y Shoulders 1'9are arranged on the member 15 for the purposeof lifting the matrices. Owingto the fact' that the matrices differ considerably from each other in'thickness, the member 15 must be wider than the thinnest matrix. If then by chance cent to each other, the member 15 must be prevented from lifting two or more matrices at the same time, which 'is'done by means of the shoulders 19. These shoulders must have 'two very thin matrices are arrangedadjathinnest matrix at the bottom, only one matrix at a time will be lifted by means of the shoulders 19 connected with the lifting device 15. In the path of the cleaning passage 14 there is also'provided an abutment 20 for the purpose of preventing a second matrix sticking any dirt mixed with benzine and clinging to 1 p the matrices is brushed off and flows down ward out of the machine togetherwith the benzine. Thedevice 24 operates in a" way whichfis similar to'that' of street cleaning machines wherein rubber plates are pushed over the pavement and brush off the dirt and water. 7 Above the cleaning passage 14 are provided two cooperating endless felt bands 25 and2'6 whichpass around rollers 27, 28, 29,30, 31 and se. A

Ofthese rollers the roller 27. is driven directly by the crank '18 and produces the move nient of the felt bands 25 and 26. At the point atwhich the bands 25 and 26, which run together 'overla portion of the'peri'phery of the roller '32, again separate, there is-ar-.

ranged the collector 33. Thevcollector .33 consists of an inclined-passage having guide 7 rails 34 provided at the sidewalls thereof.

. In thedischarge direction of the matrices 14o vided. astop 35 which limits themovement fromthe felt bands 25 and 26 there is proe of the matrices, At the lower'end of the colthrough the, brushes 22 and [23 and alsolector 33 thereis provided a matrix receiver in the'form of an angleiron 37 capable of being withdrawn an'dfinto which the matrices slide as it is withdrawn, said receiverfbing preferably'fprovided with a'handle 36. I

v The roller 29' can be adjustedfl-in-position by means of the screw 38 so asto'enable the. felt band 25 tobe ten'sioned. Underneath the. 'strippingdevice 24 openings 39 are provided in the rear wall-2 of the casing which serve for the supply ofbenzine from abenzinetank mounted on the machine or inany other suitable position. From these openings clean benzine flows in an uninterruptedcourse I through holes 40 tothe brushes 8 9,10 and 11.

The used benzine with the dissolved grease from the matrices flows through a channel .41

' into a gutter 42 and from here throughan outflow passage 43 into-a collecting tank,not

1 shown.

[:iThe method of operation is as follows The matrlces 44 to be cleaned are, as will the machine.

into the pile. When passingthe brushes 8,

9, 1 0 and 11 which are sprayed with benzine the matrices are cleaned at the edges, at the foot and at the toothed portionthereof and the grease is'somewhat softened on the wide sides and at the lugs. Asgsoon as the first matrix 44 has reached the wall 13 the crank 18, which is in its lowermos't position, is rotated and the matrix lifting device 15 is raised so that the first matrix is also raised. When assing between the brushes 22 and 23supplied'with benzine the matrix is cleaned on its wide sides'and also thelugs thereof. On passing through the stripping device 24 any cleaning material still adhering to the matrix is removed- I 1 In the meantime thecrank 18 has com-l pleted half a revolution and has reached its highermost position. This position is illustrated in Figure 2'; As will be clearly seen in this figure the matrix has already been gripped between the-felt; bands passing between the rollers27 and 28 and-on the further rotation of the crank 18 will be moved further between the bands'and dried. The matrix lifting device '15 returns to itslowermost position so as subsequently to raise va further matrix which isoperated upon in'the manner just describ'ed.f' I

When leaving the felt bands'25 and 26the I matrices reach an inclined surface on which they .slide with their-head foremost as far "as the stop 35. WVhen-m'eetingthe stop- 35 the matrices turn about their horizontal axes as indicated in Figure my reason ofthe fact I that the lugs provided at-the foot of the I 'ina'tr'ices are guided downwardly alonga curve in grooves formed between'the guide rails' 34 and the bottom of the collector 33. As soonas the matrixis vertical thelugs pro'-.
